dbe3cea002 silencing some of the warnings in OSL for OSX 2012-09-05 20:50:10 +00:00

f3a91f461c Fix for OSL memory leak. The context creation for OSL is now done in the shader_setup_* functions, since it should specific to the sample being worked on. The the context release then happens in the kernel_shader functions after shader evaluation is done. Care has to be taken to ensure the shader_release function is also called in cases where the path integration is cancelled early, this was the main cause for unreleased contexts and subsequent new allocations. 2012-09-05 08:12:22 +00:00

95b85a8c37 Revert "Use one context per OSL thread. Not sure if this actually works, but the simple renderer example in OSL does it this way."
This does not actually work: The context must not be shared between threads, but using the same context between different samples actually seems to prevent OSL from switching between shaders. The proper solution would be to ensure memory pooling works correctly.

This reverts commit 69f87e69258d6266dcb20f09f7e3d4021e663432.

ebc653463d Cycles:
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.

And a bunch of incomplete and still disabled code mostly related to closure
sampling.

bae896691a Cycles:
* Add alpha pass output, to use set Transparent option in Film panel.
* Add Holdout closure (OSL terminology), this is like the Sky option in the
  internal renderer, objects with this closure show the background / zero
  alpha.
* Add option to use Gaussian instead of Box pixel filter in the UI.
* Remove camera response curves for now, they don't really belong here in
  the pipeline, should be moved to compositor.

* Output full float values for rendering now, previously was only byte precision.
* Add a patch from Thomas to get a preview passes option, but still disabled
  because it isn't quite working right yet.
* CUDA: don't compile shader graph evaluation inline.
* Convert tabs to spaces in python files.

da376e0237 Cycles render engine, initial commit. This is the engine itself, blender modifications and build instructions will follow later.
Cycles uses code from some great open source projects, many thanks them:

* BVH building and traversal code from NVidia's "Understanding the Efficiency of Ray Traversal on GPUs":
http://code.google.com/p/understanding-the-efficiency-of-ray-traversal-on-gpus/
* Open Shading Language for a large part of the shading system:
http://code.google.com/p/openshadinglanguage/
* Blender for procedural textures and a few other nodes.
* Approximate Catmull Clark subdivision from NVidia Mesh tools:
http://code.google.com/p/nvidia-mesh-tools/
* Sobol direction vectors from:
